DQM Online training

1. Execution Environment

Request a virtual machine to the CERN Virtual Machine Service (http://vmm.cern.ch), the following are expected features:

- Operating System: SLC5-x86_64

- RAM Memory: 2GB

- CPU: 2 cores

- Hard Disk: 40G

2. DQM GUI Installation

mkdir testGui

cd testGui


svn co svn+ssh://svn.cern.ch/reps/CMSDMWM/Infrastructure/trunk/Deployment cfg

# svn co -r 15374  svn+ssh://svn.cern.ch/reps/CMSDMWM/Infrastructure/trunk/Deployment cfg #

$DQM_HOME/cfg/Deploy -t MYDEV -s "prep sw post" $DQM_HOME dqmgui/bare

3. Starting the DQM GUI server


$DQM_HOME/current/config/dqmgui/manage restart "I did read documentation"

Other options of the previous command include start, stop and status.

4. Setting the DQM GUI Index

cd $DQM_HOME/state/dqmgui/dev

visDQMIndex create ix

- In order to load a valid histogram, download one or more from https://cmsweb.cern.ch/dqm/offline/data/browse/ROOT/ and then copy them to the virtual machine

scp [root file name].root [virtual machine hostname]:/$DQM_HOME/state/dqmgui/dev/uploads/

visDQMIndex add . $DQM_HOME/state/dqmgui/dev/ix . $DQM_HOME/state/dqmgui/dev/uploads/*.root

5. STG Installation

STG is the patch manager used for the DQM GUI tool patches.

sudo mkdir guiworkspace

cd guiworkspace/

sudo mkdir Infrastructure

sudo yum install git.x86_64

sudo yum install git-all.x86_64

sudo yum install gitk.x86_64

sudo yum install gitweb.x86_64

sudo yum install stgit.noarch

mkdir ~/.stgit

ln -s stg/stgit/templates ~/.stgit

git config --global user.name "[your name]"

git config --global user.email "[your CERN email]"

git config --global svn.addAuthorFrom true

git config --global svn.useLogAuthor true

git config --global color.diff auto

git config --global color.status auto

git config --global color.branch auto

(echo "Host *" echo " ControlMaster auto" ) >> ~/.ssh/config

ssh -Nf svn.cern.ch

nano ~/.ssh/config

If it is present, delete the line: echo " ControlPath $HOME/.ssh/%h.%p.%r" and save the changes.

git svn clone svn+ssh://svn.cern.ch/reps/CMSDMWM/Infrastructure -s

cd Infrastructure/

git config branch.master.remote svn

git config stgit.pull-policy fetch-rebase

git config stgit.fetchcmd "git svn -i trunk fetch"

git config stgit.rebasecmd "git svn rebase"

touch .git/FETCH_HEAD

stg init

stg branch -c mydev

git config branch.mydev.remote svn

In your home directory:

sudo git clone git://repo.or.cz/stgit.git

cd stgit

sudo yum install asciidoc

sudo make prefix=/usr all doc

sudo make prefix=/usr install install-doc

6. Patch Management

Set $DQM_HOME as your DQMGUI installation directory.

New patches will be available in the directory:


They must be moved to the test directory:

mv /afs/cern.ch/user/c/cmsdqm/scratch/gui-patch-dropbox/* /afs/cern.ch/user/c/cmsdqm/scratch/patches-under-test/[current month directory]

In a valid STG workspace (see step 5):

cd  Infrastructure/Deployment/dqmgui/

Create the new patch that will compile all of the pending patches (stg squash option):

stg new -m "RP Layouts WS update" rp-layouts-ws-h$(date +%m%y)

For DQM general patches:

cat /afs/cern.ch/user/c/cmsdqm/scratch/patches-under-test/[current month directory]/[patch name] | patch -p[0-4] --dry-run

cat /afs/cern.ch/user/c/cmsdqm/scratch/patches-under-test/[current month directory]/[patch name] | patch -p[0-4]

For DQM STG based patches:

stg import /afs/cern.ch/user/c/cmsdqm/scratch/patches-under-test/[current month directory]/[patch name]

The for both cases:

stg series

This command should show both patches.

stg squash -n rp-layouts-ws-h$(date +%m%y) rp-layouts-ws-h$(date +%m%y) [patch name]

stg refresh

stg series

This command should show only one patch.

stg show

This command should show the mixed body of the patches.

cd $DQM_HOME/cfg/dqmgui

svn revert -R .;svn status | awk '/?/{print $2}' | xargs rm -rv; svn up ;

This command will reverts the directory to its original state and apply the lastest updates.

cd  Infrastructure/Deployment/dqmgui/

stg export -d $DQM_HOME/cfg/dqmgui -p -n

. $DQM_HOME/current/apps/dqmgui/etc/profile.d/env.sh

cd $DQM_HOME/cfg/dqmgui

cat [patch name] | patch -p[0-4] --dry-run

cat [patch name] | patch -p[0-4]

$DQM_HOME/cfg/Deploy -t MYDEV -s sw $DQM_HOME dqmgui/bare

monControl rebuild all from $DQM_HOME/current/config/dqmgui/[config file changed]

$DQM_HOME/current/config/dqmgui/manage restart  "I did read documentation".
